Method of disposing radioactive ion exchange resin.

摘要

A method for processing spent radioactive ion exchange resin formed in a nuclear power plant by a two-step pyrolysis method. First, the spent resin is heated at 350°C to decompose functional groups selectively. Then the base polymer, formed as residue, is decomposed at a temperature above 350°C, e.g. 600°C. After the thermal decomposition, exhaust gases which require a special exhaust gas disposal means, such as NO<Sub>x</Sub> and SO<Sub>x</Sub> can be reduced to below 1/20.
